I had a mystery ticking in Valve train.Cost me an engine rebuild. Mercury had defective valve springs early 500 H.P. The inner spring broke and sounded like a sticky lifter. Finally dropped a valve . $6,000 dollars later. Good Luck.

Well, we pulled the motor, unbolted the bellhousing and....all the bolts were tight! We did notice that the motor mounts were loose and that one of the spring washers was sitting in the bilge...
Upon reinstalling the motor (and properly aligning the drive) the tapping noise seems to have disappeared. I havent taken the boat out and run it yet (thats happens tomorrow) so we will see how she does after a full shakedown run.

I swear, boats and women.

Correction...she is running flawlessly BUT the tapping noise is still there. I am down slightly on power from last summer (4900 rpm vs 5100 rpm at wot) and hitting 60 mph vs 63 but otherwise it sounds and runs awesome.
I am scratching my head as to what to do at this point. Do I continue to run her? No one can seem to figure out what this tapping noise is...

No, according to Eastside Offshore (my shop) they said the tapping noise is clearly not coming from the distributor. I never found out why the rotor was damaged.

you need to find a qualified repair shop...
its hard for anybody to tell you whats wrong with your engine without inspecting it..
Find a repair shop that knows what they are doing...

I also brought the boat down to a friends house and he had a good friend of his look at it who owns his own boat shop and is a 25 year certified mercruiser mechanic. Everyone said the tapping noise was coming from the bellhousing which is why we pulled the motor and the bellhousing only to find nothing wrong.
So this is not a situation where I havent had the boat to the shop.
